Physicists from Russia, together with an international research team, have discovered that nanoparticles can be made into three-dimensional structures that strongly scatter electromagnetic waves. This can be used to create protective screens for micro and nano objects. Alexander Shalin of MIPT, one of the study’s authors, explains that this could be useful, for example, for hiding objects behind nanoparticles.

Ordinary objects interact with light and electromagnetic radiation differently than nanoparticles. This feature is used in nanodevices. While experimenting with nanoparticles made from highly refractive dielectric materials, scientists discovered an unusual effect: some particles scatter light more than expected.

This is due to resonant vibrations, which in some cases can be amplified and cause strong scattering of electromagnetic waves. Physicists made calculations and created nanoparticles of the appropriate shape, confirming their assumptions with experiments.

These nanostructures can be used as protective screens for nanoobjects and improve the performance of optical traps, cell-powered devices, and components where radiation interference is often involved.
